Back to Walbro, yes I know a lot of people use it and no issue hence I went for one but at the first mapping session, it was a little too lean when it hit 8000 rpm so Tom and Romain thought it was the fuel pump issue. So Romain locked the rev to 7500 rpm. I then changed to DW320 fuel pump got the mapping tweak and was able to map it up to 8950 rpm.
Obviously DW has better flow rate which I think it helps.

So I had my car remapped again by Romain today and i got a good result hence it's definitely a fuel pump issue. I bought it from this ebay shop; https://www.ebay.co.uk/usr/fuel-performance
and the shop confirms it's a genuine one so maybe I was unlucky and got a faulty one..don't think they will be responsible for this and to be honest, I couldn't be bothered.
Anyway, I would say if you are to buy a Walbro fuel pump, buy it from a garage that you can trust and if things go wrong, there is warranty and support for it. I opted for DW 320 and no issues..Even Romain prefers DW over Walbro...

That's a very healthy figure indeed. First time i had mine mapped i got low 330's at the wheels but TDi always print out the calculated fly figure which equated to around 370. second time i wasn't there when it was mapped but the fly figure was in the 390s so i would have guessed between 340-350 at the wheels. Not overly fussed on the figures to be honest i wanted to see how your graph looked as when Mike Hendy had his done he made great peak figure but was 20hp down mid range to me. Be good to get a rolling road day organised with some of the guys with the other supercharger kits to compare.
Hope your enjoying it.

I’m no mechanic but is that caliper the correct way up ? I understood that the bleed nipples where always meant to be at the top so the trapped air goes up and out when you bleed them . I have some cheap Rota Wheels which have very good brake clearance.... welcome to try one if you are local
